A nice well-designed room in an interesting building, located a 5-minute walk from the MRT station and about a 10-minute walk to the glorious Benchakitti Park. The staff member that handled check-in and such was friendly and efficient.
Unfortunately the building is not insulated effectively from the large road outside. It's not only the non-stop noise but also shaking and vibration from traffic that disrupts the peace. I realise it's Bangkok and can deal with normal traffic noise, but here it was very disruptive and ruined my sleep for the time I stayed there. I recommend using earplugs if you're assigned a roadside room.
